What is DC-Link Current Harmonics Analysis Method about?

This paper presents a general analytical method for calculating the harmonic spectrum of the dc-link current in voltage-source inverters (VSIs) under any load condition. The method utilizes convolution of the phase-leg switching function and load current spectra, allowing for accurate evaluation of the dc-link ripple current, which is crucial for assessing capacitor lifetime and EMI performance. The approach has been validated against experimental results across various converter topologies and PWM strategi
